Document Type and Number:

WIPO Patent Application WO/2002/040759

Kind Code:

A1

Abstract:

A stretching composite sheet comprising a stretching nonwoven fabric and a thermoplastic elastomer layer bonded to one surface of this nonwoven fabric. The stretching nonwoven fabric is formed by performing a stretchability imparting process, such as pleating, on a nonwoven fabric of non-elastic fibers and has at least 100% elongation at least in one direction. The thermoplastic elastomer layer is bonded to the stretching nonwoven fabric in such a pattern that has a directivity in a direction in which the stretching nonwoven fabric has at least 100% elengation.
